Serverless stack with CI/CD & blue-green deployments - API + Static UI + Async Tasks

Serverless Stack CI/CD

Serverless Stack with CI/CD - API + Static UI

This stack is completely serverless and powered by CIM.

It consists of:

• UI - Static S3 Website, CloudFront, SSL
• API - API Gateway, Lambda, SSL
• Async Tasks - SNS, Lambda

With every code push your Infrastructure will be updated.

With every code push a new version of your Service will be built, tested, and deployed.

There are two environments sandbox and prod. This makes it easy to test Infrastructure and Code changes before pushing to prod.

• sandbox -> development Git branch
• prod -> master Git branch

The Lambda function uses blue/green canary deployments. 5xx, 4xx, and latency are monitored to make sure the new deployment is stable.

Architecture

Pipeline

Setup

• Fork and clone this repo.
• Install CIM (CloudFormation Utility)
• Register your domain with Route53
• Or point your existing domain to Route53
• Configure '[e-mail]' to receive the SSL verification email
  • You will have to confirm this email address. This is annoying and I've asked AWS to remove this step if the domain is used with Route5
• Install the bootstrap.stack.yml stack.

Encrypt Secrets

In order to protect your configuration secrets like your GitHub token we need to create a KMS key first.

• Install https://github.com/ddffx/kms-cli and setup your AWS environment vars.
• Encrypt each string as outlined below.
• Add the encrypted strings to the _cim.yml. The format is ${kms.decrypt(<encreted string>)}

How to Encrypt

Create a file called encrypt.json

{
  "keyId" : "<your kms key id>",
  "plainText": "<your client id>",
  "awsRegion": "<aws region>",
  "awsProfile": "<aws profile"
}

Use this command to perform the encryption : kms-cli encrypt --file encrypt.json

Stack Up

Create the boostrap stack manually. Once this is complete the pipelines will be created and then create the other stacks.

• Run cim stack-up
